- Clients are assigned to team 1 in sandbox mode (because the host is also in team 1).
- Respawning characters are always assigned to team 1 (otherwise mid-round joining clients would end up in team 0 because the team assignment is done when the round starts)
- If a client doesn't enter the game within 30 seconds of starting the game, their character is automatically killed (otherwise the character would stay in-game in the disabled state indefinitely).
- Clients don't update CombatMissions if neither team has any characters (the clients may not have received messages about the characters spawning yet, which would cause them to show the "team dead" message immediately when the round starts).
- generating "dummy locations" for the MP gamesessions (visible in sonar and mission descriptions)
- EndGame network message tells the clients if the mission was successful (because the message may arrive before the sub has reached the exit or before some character has died at the client's end)
